  Conformationally defined adrenergic agents. 3. Modifications to the carbocyclic ring of 5,6-dihydroxy-1-(2-imidazolinyl)tetralin: improved separation of .alpha.1 and .alpha.2 adrenergic activities

  摘要：

  A series of modifications to positions 1, 2, and 4 of the tetralin ring of 5,6-dihydroxy-1-(2-imidazolinyl)tetralin (1, A-54741) succeeded in improving the separation of the potent alpha 1 and alpha 2 adrenergic agonism observed for the parent compound 1. In particular 5,6-dihydroxy-4,4-dimethyl-1-(2-imidazolinyl)tetralin (7) was found to be a specific alpha 1 adrenergic agonist, and 7,8-dihydroxy-4-(2-imidazolinyl)chroman (2) was found to have improved alpha 2 adrenergic agonistic selectivity relative to the parent compound 1.
